Abstract

The invention provides a wireless network backup method, which primarily establishes a wireless LAN (WLAN) providing services without disconnection. This method can provide to simultaneously install a primary connection device and another (at least) one backup connection device in a WLAN; once the primary connection is in faulty state, user still can count on the backup connection device to continuously connect with WLAN. The major features of the invention are used to control the backup connection device to detect the operating status of primary connection at any time, simultaneously back up (memorize) all configured values and working parameters of the primary connection device, such as network domain, address, channel, name or user's information, on-line information given by manager, also can simultaneously change all configured values of the backup connection device itself to differentiate them so as not to interfere the primary connection device and save the trouble for managing personnel to adjust all devices one by one. Moreover, the system diagnostic capability equipped in the invention can determine if the fault is happened from the primary connection device or backup connection device. Further combine with self-waking and parameter changing capability; when the primary connection device is found faulty, the backup connection device will be waken up and then the configured values of the backup connection device are modified to be identical to those of the primary connection device so as to further replace the faulty primary connection device for continuous on-line services. As the invention provides alert capability, which reports all faulty messages to manager to facilitate manger's understanding of system condition and quickly solve problem. The invention can also be used to integrate the primary/backup connection devices from identical vendors or different vendors and user can still maintain original system structure. Partial addition, modification are what it takes to effectively save cost and man power without having to purchase and install everything once again.

Description

569580 V. Description of the Invention (1) "Background of the Invention" If there is no way to set up personnel to go out of power, go offline, or find the next wave or cross the line, then the establishment of accounting software is still a "prepared by If you want to continue the construction of the general industry, the wireless path is convenient, the line is set on the line switch to hang or cause a problem in the job search costs the easy server, the guide is really expected to manage the database; Wireless area routers, etc., interrupt the installation of a single system and other unknown conditions, and then click on 'precious, in case a large customer database such as a device is used to tears and tears, it is time-consuming and expensive to rely on the information to make one. It ’s hard for the hardware rack to endure the construction of the network backup system of the wireless unit chiefs over and over again, and most of them have the information manpower and operators operating the customer service system damage. So that the company will not have a backup slot for the network administrator to set up a difficult incident, so as to construct a solution to the problem of love that ca n’t be brought by the disconnection, and avoid trust and control. The problem is that it is important for the user to run for a long time. However, because of the need for the operator to stay up late, but what is the only inconvenience? This case is mainly related to each other, so that if you ca n’t, you can run west. Is there any software for the inexplicable personnel plus the reduction system? ”Does the information inventor connect and interfere with the network management and be forced to climb up the meaningless database? Resilience can be controlled. The user will also provide "Invention Purpose" In view of this, the inventor of this case, based on his own experience and continuous thought research, has finally led to the development of this invention ^: The purpose of the related industries for many years is to provide a "wireless Network backup is the most important thing. "This method is mainly 569580. 5. Description of the invention (2) Use? ΐIn: No, within the local area network, the original main connection ^..., the line is changed, and the wireless router can be re-set (to the beginning of the "seven spare connection device, and controlled by this method 、 Manage this = / backup connection device, and activate it on the main connection; & + s Mao Shengjiu usually, the backup connection device can be immediately and fully self-existing # # ^ = works, becoming a temporary main connection Device, continue to come to service 'and proactively remind the information staff to handle the fault; 俟 = = when the device is removed and returned to the line, this method can be wired = the connection work in the network, and then returned to the original main connection _ ^ ^ 7-into make the main temporarily connected device back behind the scenes, and then set up a 4 times succession task, so this network service allows users to: ,, and only two more f, more automatic wireless zone energy ? put to work to put two purple ΓΓ ΐ more confidence, τ to put all Ύ inter mastiff business productivity and overall job performance "technical details, features and effects" and excellent ίί it:.

Therefore, the initial step 22 of the backup connection device 12 is completed, and it is declared to enter the backup mode = formula 2 ”Check the main The answer to the reply from the connection device is' The program 2 2 2 is finished and the program 2 2 4 is executed; Kaolian m was ί 2 2 3: It is used to check other-references in the same-area: Connect, set 1 whether to send a beacon i 6 i, if the reception result is normal: To connect the wireless end of device 1 i is abnormal, or the master = 杳 ff: 3 ends, and then return to the program "1 keep S 2 I two to Beacon 1 6 1 indicates the backup connection device] Reference; Hang 'the program ends 2 2 3, and make a log file for future reference Examination I 2 4 is the same as the examination of the inside of the wireless local area network. The answer of 1 positive i 1 5 1 is normal. If the answer is 1 5 the device line is the physical line of the LAN 1 and the backup connection. All should work normally, the program "4ί is the failure of the main connection device 2i, and the 1 will be used as a record file for later reference to the secret recipe 2 2 4 、、、 口 束, and 569580 V. Description of the invention (6) Answer 1 5 1 is abnormal, then the program 2 2 4 will determine that the device 1 2 has a problem. The program 2 2 4 ends the standard for future reference. When the system announces to enter the backup mode, step 2 3, step 2 3 through program 2 first. 3 1: Check the main connection to send out an internal access agreement (Inter Accent PrOcol) 115; if the program finds that the internal access agreement 1 1 5 exists, it means that 1 1 is a known type (same manufacturer) ) Product, after the process is completed, it enters complex mode step 2 4; if the process finds that the internal access agreement 1 15 does not exist, then the device 11 is an unknown type (different manufacturer) product, and after the execution is completed, Go directly to step 2 5 in easy mode; as for step 2 4 in complex mode, Equation 2 System parameter change procedure 3: Make the backup connection device 1 2 '俾 correspond to the set value of the main connection device 1 1 Equation 2 4 2: Continuously check the main connection device 1 1 Launch and answer 1 1 4 if The check result is normal, indicating that the main 1 is in good working condition. The program 2 4 2 will repeatedly find the beacon 1 1 3 or answer 1 1 4 when any signal is good, intermittent, or weak), indicating that the main connection device 1 Generated, the program 2 4 2 will determine the main connection device 丄 program 2 4 2 execution ends, continue to the first conversion step one conversion step 2 6 start with the program 2 6 1 call the system for the backup connection 'and make a record of the backup mode Step device 1 1 Whether ss P 〇i 2 3 1 Check the main connection 2 3 1 Execution 2 3 1 Check indicates that the main connection is the program 2 3 1 4 1 Change the difference first, and then the beacon should be connected Execution, abnormal (1 has been 1 malfunction 2 6 parameters change call system parameters through the process 1 1 3 device 1 if you check the quality without asking rhyme more
